Yes

that is indeed the purpose. I'm going to start with the EA that have very few indicators and then slowly add more exit strategies and indicators. We might also be able to do MQL to ECN conversions, and suggestions to increase profitability based on the advantages of the ECN.
We get to see how many orders are stacked up above the ask and below the bid (tens or hundreds of thousands mini lots) and we can look at the streaming data to determine if the activity is on the bid or the ask. (Which side dropping their price, and how often?) This could also lead to some interesting see saw style calculations.
The main advantage of course using MySQL over a chart is that the data can be selected and managed in more interesting ways, like the price action divided up by market. Make 100 graphs of the last JPY, London and NY open side by side, etc.
Best part in my mind: there is no broker to fight you. And of course, having spreads of 1 pip or less is also nice
